CARL RAUSCE, 0F LEIEZIG, GERMANY.

CRIPPLING-MACI-IINE.

Application filed August 20, 1913.

To all whom it may concern:

Be it known that I, CARL RAUsorn a citizen of the German Empire, andresiding at Leipzig, in the German Empire, have invented new and usefulimprovements in CripplingMachines, of which the following is a full,clear, and accurate specification.

The invention relates to a crippling machine in which the fold of thehide is rolled backward and forward between two parallel plates adaptedto be relatively moved. In existing machines of this kind the cripplingplates are arranged horizontally, so that the hide to be crippled, inorder to be able to follow the movements of the plates, must also bemoved horizontally. This has the drawback that the friction between thearts of the hide lying on each other is very great, so that under somecircumstances this friction is not overcome by the friction between thecrippling plates and hide, so that the crippling plates slide on thehide with- 'out being able to roll the fold backward and forward Thisdrawback is overcome according to the present inventlon by arranging thecrippling plates in a vertical or approximately vertical plane and bymoving them in opposite directions, the fold of the hide to be crippledresting on rods on both sides of the plates. By this arrangement thefurther advantage is obtained that the fold of the hide. durins thecriiiling )rocess always remains at the same height, so that themanipulation of the hide is much facilitated. In order, in the case ofvery rough hides, to prevent the parts hanging from the crippling platesbeing caught together, owing to too great friction,in which case therolling of the hides is rendered more difiicult, a tongue is providedaccording to the invention which from below rises between the cripplingplates and separates the parts of the hide hanging down. Great facilityin the attendance of the machine is afforded by the fact that the hideis automatically moved, so that the attendant has only to guide thesame. This automatic feed of the hides is obtained according to theinvention by reason of the fact that in one direction of motion of acrippling plate the distance between both crippling plates during theperiod of a stroke or part of a stroke Specification of Letters Patent.

is increased. Finally a device is used to compensate for the unequalthickness of the hides. One or both crippling plates consist of severalparts each of which is resilient. By this arrangement the result isobtained that when the hides have a nonuniform quality, that is, whenthin and thick places lie near together, not only the thicker parts, butalso the thinner parts are subjected to the pressure of the cripplingplates, and, consequently, also are crippled.

On the drawing one construction of the machine is shown in Figure l inside elevation and in Fig. 2 in front elevation. Fig. 3 is a sideelevation of a machine in which the hides are automatically movedbetween the crippling plates. Figs. 4: and 5 are a section and elevationrespectively of a crippling plate consisting of several independentlyresilient parts. Fig. 6 is a section showing in detail the means forlaterally moving the crippling plates.

On the machine frame a there are two slides Z) and c carrying the righthand crippling plates 71 and left hand crippling plate i and adapted tomove in vertical guides (Z and e. The guide (Z of the slide 6 is rigidlyconnected to the frame a, while the guide 0 of the slide 0 is adapted toturn about a pivot f provided on the frame a. Both slides 7), c areconnected by rods 1 to crank disks h,by which they are moved up anddown. The stroke of the crank disks is equal and these disks are sodriven that they always move in. opposite directions. The cripplingplates 2', i secured to the slides b, 0 are coated with cork or similarrough material on the surfaces facing each other.

To the guide 6 is jointed a rod 73, which by a lever Z is so connectedwith the pedal m that on pressing down this pedal the guide (3approaches the guide (Z, so that the distance between the cripplingplates 2', i is lessened. A spring it tends to press back the guide 0.

lVhen the feed of the hide between the crippling plates has to takeplace automati- Cally the crippling plate 2' is not fasteend to theslide 5 but is carried by bolts 2? which are adapted to move in theslide Z) perpendicular to the surface of the plate 6 Springs u tend topress the crippling plate 2' toward the other crippling plate 2' To thebolts 2? is connected a crank slot 12, through which passes a shaft 10.On the shaft tappets w are fastened. The shaft is adapted to slidelongitudinally, so that the tappet disk secured thereon can be moved inand out of the crank slot 1). From the driving gear of the crank shaftsh the shaft is so driven that for two, three or more completerevolutions" of the crank disks h it turns once as by gear and belt 1When a tappet disk is in the crank slot '0, the tappet in question,moves the crank slot 1), together with the bolt t, and the cripplingplate connected thereto, horizontally backward and forward, so that thedistance between the two crippling plates 6, 2' is increased anddecreased. By difierent lengths of tappets the duration of the increasein the distance of the crippling plates and .hence the period of theirseparation from each other can be regulated according to desire, whileby different angular positions ofthe tappets the time to increase thedistance is adjusted. On the shaft there are at least two tappet disks,one of which removes the crippling plate i from the crippling plate 2'when the crippling plate rises, while the other effects the sameoperation when said crippling plate 2' falls.

Underneath the two crippling plates 2' there is a large trough 0 whichtakes up the hide to be operated on, so that only a small part of thesame hangs free and can follow the movements of the crippling plates. Onthis trough rest supports 79 which carry rods 9 at the top, these rodsbeing arranged on both ends ofthe tongue between the crippling plates.These rods serve to support the hide r to be operated on, so that Saidhide can be easily moved and guided. To this trough the tongue 8 may beattached which projects from below into the space between the plates 2',and, by keeping both halves of the hide hanging from the fold apart,facilitates the rolling movement of the hide fold between the cripplingplates. I

The crippling plate 2' consists of a number of strips 1 which areconnected by springs 2 with a plate 3. Bars 4 prevent the strips 1 fromfalling from the plate 3. Each strip 1 can yield independent of theothers, so that, when hides of very irregular thickness are treated,they are pressed together by the crippling plates both at the thinnerand thicker parts.
